Button Cover

A relative has a video mixer for his church, and keeps bumping the "Fade to Black" button. This thing is to cover the button and make it harder to bump. I made two versions: one where you have to move the cover off before hitting Fade to Black; and another where you can still poke it, just not accidentally.

To use the .scad file, you need OSCAD. But if you have OSCAD, you can edit the buttons height, width, and length easily. The two .STL files are for a button 18mm x 26mm x 4mm.
